| Quench Oils are high-quality oils developed for heat treatment of ferrous metals in a wide variety of quenching operations. They are formulated to provide deep and uniform hardening with minimum distortion and cracking for a smooth surface finish. Quench Oils are available in four grades: 15, 22, 22HS and 32HS. The 22 grade is a highly refined, straight (non-additized) paraffinic mineral oil recommended for conventional quenching of ferrous metals at bath temperatures up to 150°F (66°C). It has a slower quench speed than the other grades, and provides minimum hardening power. The other three grades are fortified with select additives to provide enhanced oxidation resistance and metalwetting ability for use in fast quench operations where it is important to develop maximum hardness while minimizing distortion. The 15 and 22HS grades are high-speed quench oils with moderate-to-high hardening power. The 32HS grade is a higher viscosity, high-speed quench oil that provides the highest hardening power. Quench Oils provide a high initial cooling rate to induce maximum hardness. After the critical transformation temperature is passed, the cooling rate gradually decreases to a much slower rate to minimize the possibility of stress and metal distortion, thereby ensuring a smooth surface finish. These oils are highly stable throughout the hardening temperature range to provide long service life with minimal sludge formation. They have a high viscosity index for minimum viscosity change during the entire quenching operation, and have high flash and fire points to minimize fire hazards. Applications: - Conventional and fast quenching of ferrous metals, such as carbon steel, gray iron and high-alloy steel
